QC for Raw Powder in Metal/Ceramic Injection Moulding

Phaos Case Studies

It has always been a challenge to assess the quality of an injection mould as the quality check is only possible after de-binding and sintering. This, in turn, leads to possible quality problems in the end products. Hence, to rectify this issue, a preliminary assessment of feedstock quality is of decisive importance.

For metal and ceramic injection moulding, users can pre-examine the quality of the raw powder to determine the quality consistency in all of the batches. This is because the finished products are highly dependent on the quality of the raw materials.

Quality of the raw powder are classified based on:

  1. Size Uniformity of the Powder
  2. Presence of Powder Agglomeration
  3. Conformity of Powder Shape

However, powder morphology characterization remains a challenge under conventional optical microscope.

Given the irregularity of particles and uneven distribution of powder size, it refrains to fully resolve with the shallow depth of field by optical microscope.

These constraints give a halt for the user to use the optical microscope and deviated to use a sample preparation hectic and time-consuming scanning electron microscopy (SEM) instead.

With Phaos’s Optical Microscopy System, micron to nano size powder can be resolved completely.

With the easy operating machine without considering the sophisticated parameter and procedures like any other microscopy system, an image can be obtained within seconds. Faster quality control examination translates to more reliable and faster production yield.
